Application mea April se, 1921. serial ne. 186,684.

This invention as indicated relates to a window construction. Moreparticularly sald invention includes a frictional suspension for awindow and means for controlling the same.

It also'includes an interlocking lrela-tion between the window sash andthe window frame whereby the support at one side of the window coaetswith the support on the opposite side of the window both with respect tomovementin the'plane of the window and transversely thereof with meansfor adjustlng the degree of tension or pressure applied at elther sideof the window. It also has in view selfadjusting `guide members whichwill automatically compensate for expansion-or contraction of woodenwindow frames and sashes and present binding action or'undue freedom ofmotion. It ,also contemplates dispensing with a parting strip andvertical stops in a window construction, and includes features ofconstruction incidental thereto.

To the accomplishment of the foregoing and related ends, said invention,then consists of the means hereinafter fully described and particularlypointed out in the claims.

The annexed drawing and the'following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but several of various mechanical forms in whichthe principle of the invention may be used.

In said annexed drawing:

As is clearly shown in Fig. 1 of the drawing, the window constructioncomprises a frame 1 which may be formed without vertical stops and withflat vertical faces against which resilient guide strips 2 preferablyterminating in beaded edges 3 are adapted to be secured. The guidestrips have flattened portions 4.- at their extreme edges which aresecured by means of'screws 5 or the like to the window casing. Thestrips are formed with an intermediate curved portion 6 which causes 70said beaded portions to be spaced outwardly from said casing. Anadjustingscrew 7 1s secured through said intermediate portion of saidguide members, said screw preferably havin a screw-threaded shank 8 andan enlarge head portion 9 between which is provided-a narrow neck rtion10. The head is preferably polygons. in shape to permit ad- )ustment ofthe yscrew by means of a wrench.

The threaded shank of the adjusting screw is adapted to be received .inan internally screw-threaded socket 11 embedded in the vframe or casing.vOpposite the position of the sockets, which are mounted at spacedpoints along the frame, each resilient guide strip is provided with aslot 12. Each slot is formed with a narrow portion adapted to engageover the neck portion of the adjust` ing screw, and with an enlargedortion permitting the ready engagement o the ad]u`st ing screw with itssocket when the parts are assembled. A shield (not shown may beappliedover open (portion of the s ot if it is desired to make theconstruction substantially water tight.

When the parts are engaged in operative p'qsition, the rotation of the,screws in one direction will bring the inner shoulders adja-y cent thenarrow neck portions against the resilient strip and force it outwardly,and rotation in the opposite direction will bring the outer shouldersinto action and will positively move the resilient strip inwardly. Thuspressure or tension may be provided for its action relative to itscoacting guide member resently to be described.

e window sash, if of metal, is preferably provided with grooved lateraledges and if of wood, is preferably channeled to receive a grooved metalguide plate. The grooved member in cross-sectional outline is preferablyof more than semi-circumferential extent so that it may be engaged aboutsaid beaded edge of the resilient guide strip, heretofore described.

While a degree of friction sufficient to support a window in openposition may be secured by having the area of contact of the groovedmembers and guide strips of large extent, it is desirable that thedegree of friction be controlled. -Where the device is applied tostructures subjected to great vibration as ocean vessels, railroad ears,or motor vehicles, it would be desirable to use grooved membersextending almost around the beaded members vand apply a high degree oftension to the resilient guide strips so as to suspend the window firmlybetween spring members.

For certain installations such as those requiring the ready removal ofthe window, or an equivalent structure, such as a screen, the groovedmember may be formed with a shallow groove not engaging about the beadeded eof the strip, but in such constructions adjustment of the frictionmust be provided for/solely through control of the pressure of lheresilient strips inwardly toward the win- Where the construction is tobe used in small boats, or in motor vehicles, or other instances, wherea single window, or a single movable window sash is required only asingle resilient guide strip need be provided at each side of thewindow, and the flat marginal portion of the guide strip may be se curedto the outer or inner portion of the frame as desired. Where upper andlower movable window sashes are required, as in most dwellings and otherbuildings, the invention provides for the omission ofthe vertical stopsand the parting strip now commonly used. Thus, as is shown in Fig. 2 ofthe drawing, the upper sash 21 is supported upon guide strips 22 securedto the frame outside of the plane of the window, and the lower sash 23is supported upon guide strips 24, secured to the' frame. on the insideof the v plane of the window. The upper frame memer 25 of the upper sashis provided with abeveled. face to Contact with a like face on a stop 26at the top of the frame, and the lower frame member 27 of the lower sashis likewise bev- The other lower and upsashes are beveled, to coact witheach other Vwhen the windows are in closed position.- It

will be noted that the resilient guide strips are slightly sprung apartas the beveled facesreferred to arebrought into contact and the windowsheld irmly in closed position.

completely In order to prevent air or moisture enter;v

ing between the resilient guide strips, where the usual parting stripbetween the upper and lower sashes is dispensed with, an intermediatestop 33 is provided (see Fig. 9) between the resilient strips at eachside of the frame at the meeting line of the upper and lower sashes. Thestop is preferably a member formed with a flange 34 for securing thesame to the frame and provided with channels 35, 36, on its upper andlower sides, adjacent its respective lateral edges. The channels arewidened adjacent the flange 34 and are open at the narrower ends. Stopblocks 37, 38, secured respectively to the lower portion of the uppersash and the upper portion of the lower sash (see Figs. 10 and 11) andextend into the space between the resilient guide strips, thenarrow'neck portions 41, 42, of

said blocks not interfering with the free sliding action of the Windowsashes on the guide strips. The stop block 37 is adapted to engage intothe channel 36 of the intermediate stop and the stop block 38 with thechannel 35. The contact faces 43, 44, of the stop blocks may be slightlybeveled to coact with in any desired position. Where very heavy windowsare to Ibe euipped with resilient guides, it may be found desirable-toprovide counterweights and cables and pulleys. These may be concealedbehind the resilient guide Strips which are made of larger size. In suchconstructions the use of parting strips between the upper and lowersashes would also be desirable to facilitate making the constructionweather tight. In .the modified form of construction shownin Figs. 7 and8, the lateral edge of the sash 51 carries a guide member 52 formed witha bead at its outer edge. A resilient strip 53 secured to the frame isfolded upon itself to provide a groove 54 at its freel edge and has arearwardly projecting flange 55 providing a housing for thecounterweight.

The counterweight 56 is supported on a cable 57 extending over a pulley58 supported at the top of the guide strip on a pivot pin 59 supportedin ears 61 inte rally formed in said gulde strip. The cable 1spositioned by said pulley centrally over the groove in the guide strip.

The resilient guide strip 53 is provided with adjusting screws 62 tocontrol the tension or pressure upon the beaded guide member. Inaddition there is provided means for adjusting thefriction of the grooveupon the beaded guide. This comprises an adjusting screw 63 engagedinthe rearwardly extendin flange and passing through an aperture in t ebody portion of the resilient strip and controlled by means of a thumbnut bearing against the body of said strip. Thus by means of said nutthe clamping action of the grooved member may be controlled.

Other modes of my invention may be employed instead of the oneexplained, change being made as regards Lthe mechanism herein disclosed,provided the interengaging and interlocking to prevent lateralseparation, and` means operable in either direction for adjusting .the'amount of such frictional engagement.
